A kind of air energy plant active substance extraction system

Abstract

The invention relates to an air energy extraction system for plant active substances, comprising an extraction tank, a vacuum concentrator, a condenser, a first heat exchanger, a second heat exchanger and a refrigerant circuit, the extraction tank is used for extracting plant active substances, and the vacuum The concentrator is used to concentrate the extracted plant actives and separate the solvent. The condenser condenses the solvent from the vacuum concentrator and supplies it to the extraction tank. The first heat exchanger includes mutual heat exchange heating water pipes and refrigerant heat exchange The heating water pipe supplies heat to the extraction tank and the vacuum concentrator; the second heat exchanger includes a cooling water pipe and a refrigerant heat exchange pipe that exchange heat with each other, and the cooling water pipe supplies cooling to the condenser; the refrigerant circuit is formed by the first heat exchanger The refrigerant heat exchange tube in the second heat exchanger, the refrigerant heat exchange tube in the second heat exchanger, the refrigerant pipeline and the compressor are connected to form a refrigerant circulation loop. Compared with the prior art, the invention improves the integration degree of the system, improves the production efficiency of the system, and reduces the energy consumption of the system.

Description

technical field [0001] The invention relates to a plant active substance extraction system, in particular to an air energy plant active substance extraction system. Background technique [0002] Such as figure 1 As shown, a traditional active substance extraction system usually consists of an active substance extraction unit, an active substance vacuum concentration unit, and a heating and cooling unit. Wherein the active substance extraction unit is mainly composed of an extraction tank 1, a first storage tank 4 and a mixing pipeline 21 connected between the two, wherein the first storage tank 4 is used to store the mixed solution of the plant active substance and the solvent, mixing Pipeline 21 is used for the delivery of plant active matter and solvent mixture; active matter vacuum concentration unit is mainly composed of vacuum concentrator 2, condenser 3 (using vacuum condenser) and second storage tank 5, vacuum concentrator 2 and the second A storage tank 4 is connec...
